TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 459,077, datedSeptember 8, 1891. Application filed January 23, 1891. Serial No.378,775. (No model.)

T0 at whom it may concern:

Be it known that I, JOSEPH LAUHOFF, a citizen of the United States,residing at Detroit, county of IVayne, State of Michigan, have inventeda certain new and useful Improvement in Tobacco-Pipes; and I declare thefollowing to be a full, clear, and exact de scription of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to new and useful improvements in a tobacco-pipe;and it consists of the devices and appliances hereinafter specified andclaimed, and illustrated in the accompanying drawings, in which Figure 1is a vertical longitudinal section, and Fig. 2 1s a separate View, ofthe passage b My invention is designed particularly to provide a pipeadapted to remove the nicetine and separate it from the smoke before thesmoke passes therefrom, thereby overcoming the deleterious eifectsthereof. Accordingly I carry out my invention as follows:

A represents the main pipe-bowl, the same being preferably provided withan interior metallic bowl or shell A, removable therefrom and formingthe base of the completed bowl, as shown at A said base being providedwith a passage a therethrough. The lower end of the bowl A isscrew-threaded, as shown at a. The interior bowl A, it will be observed, is of the nature and form of a cartridge-shell. A is aperforated cap for the bowls A A.

B is an intermediate pipe-section constructed to have ascrew-threadedengagement with the bowl A, as shown at Z2. The outer end of saidsection is provided with a wall I), through which is led a tube barranged to project through the passage Ct in the interior bowl A whenunited to the bowl A. The opposite end of the section B is constructedwith a chamber B, the wall of which is suitably screw-threaded, as shownat Z1 The end of the tube 19 is preferably extended from the wall Z)into said chamber, as shown.

C is an additional section or stem of the pipe, screw-threaded, as shownat c, to engage with the section B.

The forward or outer end of said stem is constructed with a chamber C,communicating with the chamber B when the parts B and C are united. Thestem (3 is provided with a tube 6, projecting forward into the chamberC, as shown. It will be seen that the chamber 13' C forms anintercepting smoke chamber, and one in which nicotine may readily bedeposited, since the smoke passing in to said chamber first fills thechamber instead of passing continuously and uninterruptedly into thetube 6', a space being left between the adjacent terminals of the tubesb e. Nor does the smoke pass into the tube e from the extremity of thechamber C, in which case there would be liability of the nicotine beingdrawn into said tube 6; but inasmuch as the smoke must enter from theforwardly-projeeted end of said tube this liability is overcome.

I do not limit myself to any particular material from which the variousparts above enumerated shall be constructed; but the bowl A and sectionsB C may be constructed of wood, while the inner bowl A and the tubes 1)and 6 may be made of metal. The section 0 may be shaped as desired toconstitute or connect with a mouth-piece. To still further facilitatethe removal of the nicotine from the smoke in its passage through thechamber B O, my invention contemplates such a formation of the tube 6 asto spread the smoke emerging therefrom into said chamber. Accordingly Iprefer to construct the projecting end of said tube b with an enlargedclosed end, as shown at I)", the side Wall being formed with lateralopenings 1), through which the smoke must pass into the chamber B C, thesmoke being spread laterally into said chamber as it enters the same.This will effectually throw off the nicotine to the sides of saidchamber and free the smoke therefrom in its further course through thetube 6. As shown, the stem 0 extends in a direction longitudinal to thebowl; but I do not limit myself thereto.

It is evident that the device might be used as an inhaler as well as atobacco-pipe, and my invention contemplates both.

Vhat I claim as my invention is- A pipe consisting of a bowl, an intermediate section secured thereto and provided with an enlarged chamber B, atube 19 projecting through the forward end of the inter- In testimonywhereof I sign this specificamediate section and provided at its rearend t-ion in the presence of two witnesses.

with an enlarged chamber having openings in its sides, and themouth-piece 0, having a chamber 0 secured to the intermediate sec-'Witnesses: tion, and provided with a tube e, projecting N. S. WVRIGHT,forward of the rear Wall of said chamber C. JOHN F. MILLER.
